No idea what their actual reasoning is, but here's how I think about it: This is better for novices, because otherwise you create a whole bunch of land mines for people who are desperately trying to get something done. If they aren't aware of the built-in then they aren't trying to use it. Insisting that they become aware of something they don't want right then will be frustrating. It's also better for experts, in that they're generally aware they're overriding a built-in and are doing it on purpose, and if not they'll have an IDE or linter reminding them. To me, I see tooling as a spectrum from supportive to controlling. Python is very much on the supportive end. It feels controlling when I get interrupted because some programmer who has never met me programmed a tool to insist I do things their way. That would very much include insisting I respect a bunch of names they decided long ago to put in the global namespace.
